Description
Patented Sept. 22, 1931 UNITED' STATES PATENT OFFICE GEORG KBANZLEIN' AND HEINRICH VOLLMANN, OF KEORT- ON THE MAIN.-
HOCHST, GERMANY, ASSIGNORS TO GENERAL ANILINE WORKS, mo. OF NEW YORK,
N. Y., A. CORPORATION OF DELAWARE rnocnss or mmme AND rnm'rme VEGETABLE rnmns 80 Drawing.
C ur present invention relates to a new process of dyeing and printing vegetable fibers.
It has already been known for some time 5 that 3.4.8.9-dibenzpyrenquinone-5.10 and derivatives thereof are capable of dyeing vegetable fibers from the vat intense tints (cf.- U. S. patent specifications No. 1,564,584 dated December 8, 1925, and No. 1,582,475
dated A ril 27, 1926, and U. S. patent appli-- or warm vat. The dyestuffs of the 4.5.8.9-
diben zpyrenquinone-3l0 class are also eminently suitable for calico printing. For this purpose, most dyestufi's of this class can be utilized in an unreduced state as well as in a previously reduced state. The dyestuffs Application flledluguit 2.192s. Serial 110. 297,105.
yield in almost all cases brilliant tints vary,- ing' from orange to violet of good to very good fastness properties. Since clear red vat dyestnfis fast to washing and to light are still scarce, it is a considerable advantage of the above-mentioned class of dyestuffs that it contains a particularly large number of red dyestuffs ielding dyeings from yellowish scarlet to luish-red. V
The following examples illustrate our invention, but they are not intended to limit it thereto the parts are by weight:'
1. A vat is prepared from 2 parts of 4.5.8.9-dibenzpyrenquinone-3.10 in the form of a 10 per cent paste, 1 part of caustic soda solution of 40 B., 0.8 part of hydrosulfite concentrated powder, 10 parts of calcined sodium sulfate and 200 parts of distilled water. 4
When after hour the vat has formed, there are introduced into it 10 parts of cotton yarn which are dyed'at 20 C. to 30 C. for hour. The material is then rinsed, soaped at boiling temperature and rinsed again. Thus an intense clear scarlet dyeing is obtained of good fastness properties.
In the same manner the material may be dyed with one of the following substituted 4.5. 8.9 dibenzpyren 3.10 quinones. The no shades of dyeings obtainable therewith are indicated in the following table:
Conatitutlou- Dy ng- Clear orange red Clear reddishorange 7 01amscarlet (or isomeric bodies) 0 Clea: bluishm CH;
2. A vat is prepared from 2 parts of dibromo-4.5.8.9-dibenzpyrenquinone 3.10 (obtainable bybrominating 4.5.8.9-dibenzpyrenquinone), 1.4 parts of caustic soda solution of 40 B., 0.8 parts of hydrosulfite concentrated powder, 5 parts of calcined sodium sulfate and 200 parts of distilled water.
The preparation is allowed to stand at 50 C. for 4 hour and the-material is then dyed in the vat thus obtained at the same temperature for hour. The material is soaped and rinsed, whereupon a dyeing is obtained of an intense bluish-red tint.
We claim:
1. The rocess which consists in dyeing vegetable ber with a dyestufi of the following formula:
wherein R stands for hydrogen, halogen or alkyl.-
2. The process which consists in dyeing vegetable fiber with the dyestufi of the following formula:
wherein R stands for hydrogen or halogen,
the shades thus produced on the material varying from orange to scarlet and possessing good fastness properties.
5-. Material prepared from vegetable fibers dyed with .the dyestufi of the following formula:
115 the shade thus produced on the material being an intense clear scarlet of good fastness properties.
6. The rocess which consists in dyeing ve etable her with a. dyestufi of the 4.5.8.9-
20 di nzpyrene-3.10-quinone series by one of the usual methods used. for dyeing with yatdyestuffs.
In testimony whereof, we aflix our signac tures.
